(NAPS)—Whether it’s the day you pop the question, an anniversary or any special occasion, nothing says “I love you forever” quite like a diamond.

But while love may be blind, there are a few things you should keep in mind before heading out to buy that diamond engagement ring or, in fact, any diamond gift.

First, understand what the 4Cs are. These are the four factors that determine the value of the diamond, and thus the value of the ring.

A good way to learn about the 4Cs—which are cut, color, clarity and carat weight—is to visit www.adiamondisforever.com.

Next, set a budget: Determine how much money you want to spend before you go into the store and stick to it. For diamond engagement rings, two months’ salary is a good starting point. Now you’re ready to go to a reputable jeweler in your area. Before you do, ask friends or co-workers for recommendations.
